Connecting USB-to-Serial Comm Port

Getting through the serial port on windows 8.1 annoys me. Because of the incompatibility of PL2303 drvier,
the connection just didn’t work out. Fortunately, I have found a old version driver that could satisfy
the requirement.

Let’s see the WRTNode PIN, and find out the correspondance between WRTNode pin and USB port.

Now, what we need to do is connect the wires according to the colors.

Don’t forget the power, USB wire connecting to the laptop is ok.
